Ms. Mock is thinking of two numbers that sum to 323. The smaller number is 131 less than the larger number. What are the two equations that will create the system to solve this problem?
x = smaller number
y = larger number
x + y = 323
x = y-131

What is the correct three steps to graph a linear equation from slope-intercept form?
1.) graph the y-intercept
2.)use the slope (rise then run) to move to the next point.
3.)connect the two lines with a straight edge.

How do you know if a function is a linear one? You must answer all three.
1.) Graphically?
2.) From the table?
3.) From an equation?
1.) Is a straight line
2.) has a constant rate of change in delta y/delta x
3.) the highest exponent is 1 and x is only in the numerator position.
